产品详细

现在被广泛采用的环氧乙烷水解生产乙二醇的工艺会伴生一定量的醛类物质,虽然经多步精制提纯，乙二醇最终产品中仍含有微量的醛，而醛含量是乙二醇产品的一项重要质量指标。至此在由扬子石化提出后，我公司进行产品的研发及试验，扬子石化负责进行树脂脱醛性能的评价，双方共同研制成功了YJ-1乙二醇脱醛催化剂树脂，其脱醛性能达到了国外同类产品的指标要求，在2002年11月28日通过了中国石化股份有限公司的产品鉴定并陆续在中石化、中石油乙二醇装置上广泛应用。

Ethylene oxide hydrolysis is widely used to manufacture ethylene glycol (MEG). During the manufacturing process, some impurities, such as aldehydes, are produced. Even after several times of rectification, there are still some aldehyde residues in the final MEG product. These aldehyde residues affect the quality and limit the Meg's applications.So that, Suqing Group and Yangzi Petrochemical jointly developed YJ-1 aldehyde removal resin specific for ethylene glycol.On Nov 28 of 2002, YJ-1 passed the new product appraisal presided by Sinopec Co., Ltd. Since then, YJ-1 is widely used by the manufacturers of MEG in China.
